**5.1. Primary level**

Several E-Cubers **BUILD** workshops were held which engaged more than 100 students between 2014 and 2018. The focus at this level was to determine if the concepts of *Equipment* with *Functions* which can be *Tested* could be imparted with" *ag spraoi agus ag imirt"* as a precursor to understanding OEE. All the workshops utilized LEGO® TECHNIC pull-back racers. They cost approximately €25, have less than 150 pieces. They take less than 30 minutes for an experienced builder to build but a novice can build them in less than 60 minutes.

A very small minority of students were clearly *Dramatists* as opposed to *Patterners* and were totally averse to following the detailed instructions. But most of the students enjoyed the build process even though less than 10% of the boys and less than 2% of the girls had played with LEGO® TECHNIC before. Without exception all the students could understand the fundamental concepts of equipment, functions and testing. But their desire for *imirt* was extremely strong. They wanted to create a competition and that is exactly what we did. We created an *E-Cubers OEE Game* based on the pull-back racers which were conducted over 300 seconds. Each team of two (who had completed the BUILD process) could test the OEE of their racer on a 2-meter-long race track with a defined start line and a defined *"landing zone"*. The three standard components of availability, performance and quality were utilized to calculate OEE and the formula was explained to the students. The performance was calculated based on the number of cycles (attempts to land in the zone), the quality was calculated based on the number of good cycles (attempts which landed in the zone) and the availability was calculated based on how many seconds during the 300 second OEE Game that the equipment was working correctly. Even though there were no prizes on offer the *imirt* really did bring *Passion* to the *Project* as they collaborated with their *Peers* to get the highest OEE.

Even though the E-Cubers **BUILD** workshops were extremely successful at achieving the stated objective, several lessons which were learned which should be shared. Do not hold *"free events"* which are open to the public. There will be a significant variation in age groups and capabilities which make them virtually impossible to control. Where possible utilize the teacher to organize the workshop in their own school because they are a known authority figure and well respected by the students. Be very organized and ensure that all the sets have all the components. Get the students to do a stock-take before they start; this eliminates the *"a part is missing"* scenario. But most of all do not forget that you are "*ag spraoi agus ag imirt"* and enjoy the *Passion;* it truly is contagious.
